Next, the operation and effects of the activated carbon quantitative injection device for water purification plant according to one embodiment of the present invention configured as described above will be described.

First, when activated carbon is loaded by the transfer means (not shown) in which the activated carbon is stored in the bag holder 14 of the storage hopper 10, the activated carbon inlet 15 filters foreign substances, and the storage hopper ( When the slaked lime is introduced through the slaked lime inlet 16 of 10), since the rotating shaft 4a is rotated in accordance with the drive of the geared motor 4, the spiral shaft that is supported by the plurality of supports 5 on the rotating shaft 4a. As the stirrer 20 is rotated, the hydrated lime / activated carbon is stirred and mixed.

The hydrated lime / activated carbon mixed as described above is rotated while the fan 33 of the discharge means 30 installed in the lower portion of the storage hopper 10 is interlocked with the rotation shaft 4a of the geared motor 4. It is discharged to the grinder 40 through the through-hole 31a formed in the press 31.

The hydrated lime / activated carbon discharged to the grinder 40 through the discharge means 30 is rotated as the sprocket 44 is rotated by the driving force of the drive motor 7 transmitted from the grinder 40 through the power transmission means 70. As the rotary shaft 41 is rotated, the rotary shaft 41 is discharged to the supply means 60 while being dispersed by the grinding blades 42 provided to be staggered at a predetermined distance from each other.

In other words, the grinder 40 rotates the first sprocket 64 which receives the driving force of the driving motor 7 driven according to the inverter signal output from the second inverter 6 through the first chain 71. The second sprocket 65 is rotated to rotate, and the rotational force of the second sprocket 65 is transmitted to the sprocket 44 through the second chain 72, so that the rotary shaft 41 of the grinder 400 is rotated Accordingly, the rotary shaft 41 is discharged to the supply means 60 while being dispersed by the crushing blades 42 are provided staggered at a certain distance from each other.

The calcined lime / activated carbon introduced into the supply means 60 is driven by the rotation of the first sprocket 64 of the power transmission means 70 which receives the driving force of the drive motor 7 through the first chain 71. It is discharged to the dissolution tank 50 through the discharge port 68 by the rotation of the transfer screw 61 is interlocked. At this time, the calcined lime / activated carbon introduced into the supply means 60 is not cured because it is heated by the heater 110.

Slaked lime / activated carbon introduced into the dissolution tank 50 is mixed with water to be purified in accordance with the operation of the mixer 52 installed on the rotating shaft of the mixing motor 53 while the odor is adsorbed by the activated carbon is activated carbon outlet 55 Is discharged to the outside through, and the suspended solids contained in the water to be purified in the dissolution tank (50) is precipitated with the lime and discharged to the outside through the drain pipe (54).

In the above description, the weight of the calcined lime / activated carbon introduced into the storage hopper 10 is determined by the weighing means 80 which supports a plurality of brackets 11 installed on the outer side of the storage hopper 10. The weight of calcined lime / activated carbon measured by the weighing means 80 and the amount and quantity of calcined lime / activated carbon discharged through the discharge means 30, the amount of hourly discharge, and the flow rate ( The flow rate flowing into the dissolution tank 50 measured by 90 is displayed on the display means 120.

Then, when the amount of calcined lime / activated carbon to be injected is input according to the amount of water to be purified introduced into the dissolution tank 50, the controller 1 changes the frequency to the first and second inverters 2 and 6. Since the output signal, the rotational speed of the geared motor (4) and the drive motor (7) is variable in accordance with the frequency signals varied in the first and second inverters (2, 6) to the agitator (20) and By varying the speed of the discharge means 30 according to the driving speed of the geared motor 4, the stirring speed and the discharge speed of the slaked lime / activated carbon are varied, and the grinding speed and the feed rate of the slaked lime / activated carbon are changed to appropriate amounts of slaked lime / activated carbon. It is supplied to the dissolution tank (50).

On the other hand, the system trouble, for example, the failure of the first and second inverters (2, 6), the failure of the geared motor (4), the slaked lime / activated carbon overload or lack of residual amount, the failure of the heater 110, etc. An alarm sound may be output from the means 130 to prevent a safety accident in advance.

As described above, according to the activated carbon metering device for water purification plant according to the present invention, the stirrer and the discharge means in the storage hopper are driven by a geared motor, and the driving force of the drive motor is driven through the power transmission means according to the amount of water to be purified. And it is controlled to supply the limestone / activated carbon while driving at the same speed to deliver to the supply means, it is possible to quantitatively input the amount of slaked lime / activated carbon input to remove the suspended matter and odor components in the water purification plant, and also wet activated carbon Since it is added to the water purification plant together with slaked lime, it has a very good effect of not being blown by the wind.
